A passport stamp is a rubber stamp inked impression received in one's passport upon entering or exiting a country. Passport stamps may occasionally take the form of sticker stamps, such as those from Japan. Depending on nationality, a visitor may not receive a stamp (unless specifically requested), such as an EU citizen traveling to another EU country. Most countries issue exit stamps in addition to entry stamps. A few countries only issue entry stamps, including Canada, United States, New Zealand, and the United Kingdom. Hong Kong does not issue both entry and exit stamps, issues landing slips instead. Japan does not issue entry stamp, but entry sticker intead, and issue exit stamp. Visas may also take the form of passport stamps.
